Ever get frustrated with getting stuck in the LS tunnel (to the West of the airport) and the SF tunnel (north end of SF)? Here is a fix for it. The only thing I did was change the collision files (.col) for the two items in question. Just download and replace both .col files in your gta3.img file and you'll never get stuck with a truck/trailer again! Hope you all enjoy!
